1. The activated carbon filter has subjectively for me personally no effect, and I personally perceive no odor removal. Weighs mE only about 125 grams (A50 - medium model). The IQAir weighs mE 2,5KG the middle model.
2. The effect of Plasmacluster generator has personally subjectively no effect for me.
3. The evaporation filter is to get customers in various cleaning technically barely under control.
4. Evaporation filter stinks. Guarantee application is rejected.
6. cleaning effort considerably higher than anticipated at me. Cleaning interval indicator lights every 720 hours of operation. Personally, I must at least once a week, clean the unit. Sometimes even after 2 days due to musty smell, the humidifying function is turned on so far. Water change every day.
7. Ongoing charge me also significantly higher than expected. In my experience, the evaporation filter might best be changed annually. The carbon filter I change not at first, because I can personally see any subjective effect. The Hepa be seen. Looks now after a few months but already very dirty and I believe that at the lowest level of the air flow already for me is noticeably shorter than normal. The filter prices I consider to be very expensive.
8. No round circumferential seal for the Hepa filter
9. In a direct volume comparison, a comparative product showed (with the same volume indication) a my feeling significantly lower running noise than the Sharp50 on.
10. odor sensor makes little sense in my opinion, because the device does not get reduced to barely a smell of my feeling. So the display is sometimes even for hours on red.
11. Service of Sharp I consider to be inadequate because of my experience with various devices.
12. Arrangement of the handles very inconvenient and it is heavy. Must front body up the stairs to be carried high with both hands, which is quite difficult for me.

What Unfallkasse Post and Telecommunication, Ökotest and the Federal Environment Agency say about humidifiers, you can see in the article bacteria habitats and spurs spinning the UK PT. (Ukpt.de/pages/publikationen/zeitung.php?mid=20110304)

Sharp is to my knowledge no one disinfectant, which is then added to the water and it is also used no silver ions stick. The evaporation filter is to be coated but mE (?). However, as I may find the problem with the musty smell as harmful to health, I think the device is not recommended.

Here at Pure Air Purifier - be evaded - without humidifying. The application of an evaporation device seems to me (ie with heat) as hygiensch better than the evaporation principle.
